Abstract

The invention provides an interface circuit, a signal transmission circuit and electronic equipment, and a control unit is configured to control a second on-off unit and a first on-off unit to be turned off when a target pin needs to output a high-level output signal; when the target pin needs to output a low-level logic state signal, the second on-off unit is controlled to be switched on, and the first on-off unit is controlled to be switched off; when the target pin needs to output a low-level digital communication signal, the first on-off unit is controlled to be switched on, and the second on-off unit is controlled to be switched off; the feedback unit can be used for feeding back a first signal to the control module in response to a high-level input signal when the target pin obtains the high-level input signal; and when the target pin obtains a low-level input signal, a second signal is fed back to the control module in response to the low-level input signal.
